I weigh 250-ish. I have a Soho-S with Shimano R540 and a 15t Surly back there. I have bikes in CF, chromo, and aluminum. I say don't fret the weight-limit or an aluminum bike feeling too stiff to rattle 250-pounders like us. Our poundage tends to "mute" most road rattles, if not all, no matter what time of material the frameset is....and I often ride it in fixed with 100~120psi in the clinchers. Its blast....I think you'll like it.
